1 Installation instructions
2 =========================
4 The Btrfs utility programs require the following libraries/tools to build:
6 - libuuid - provided by util-linux, e2fsprogs/e2fslibs or libuuid
7 - libblkid - block device id library
8 - liblzo2 - LZO data compression library
9 - zlib - ZLIB data compression library
11 For the btrfs-convert utility:
13 - e2fsprogs - ext2/ext3/ext4 file system libraries, or called e2fslibs
15 Generating documentation:
17 - asciidoc - text document format tool
18 - xmlto - text document format tool
20 XATTR library should be provided by the standard C library or by
22 - libattr - extended attribute library
24 Please note that the package names may differ according to the distribution.
25 See https://btrfs.wiki.kernel.org/index.php/Btrfs_source_repositories#Dependencies .
31 To build from git sources you need to generate the configure script using the
36 To build from the released tarballs:
42 You may disable building some parts like documentation, btrfs-convert or
43 backtrace support. See ./configure --help for more.
45 Specific CFLAGS or LDFLAGS should be set like
47 $ CFLAGS=... LDFLAGS=... ./configure --prefix=/usr
49 and not as arguments to make. You can specify additional flags to build via
50 variables EXTRA_CFLAGS and EXTRA_LDFLAGS that get appended to the predefined
51 values of the respective variables. There are further build tuning options
52 documented in the Makefile.
54 $ make EXTRA_CFLAGS=-ggdb3
56 The build utilizes autotools, dependencies for generating the configure
64 Statically built binaries
65 -------------------------
67 The makefiles are ready to let you build static binaries of the utilities. This
68 may be handy in rescue environments. Your system has to provide static version
73 $ make btrfs-convert.static
75 The resulting binaries have the '.static' suffix, the intermediate object
76 files do not conflict with the normal (dynamic) build.
